Sally S Key Lime Bars Recipe

Transport yourself to a tropical paradise with Sally's irresistible Key Lime Bars! This recipe, originally found on a Land O'Lakes box and perfected by our neighbor Sally, delivers a refreshingly tart and sweet treat perfect for summer gatherings. Made with the bright, tangy zest of key limes (or bottled key lime juice if fresh limes are unavailable), this recipe boasts a buttery shortbread crust and a creamy, dreamy filling, all topped with a zesty lime frosting. For the most authentic flavor, use yellow key limes – green limes are unripe and lack the necessary juice. Get ready for a taste of sunshine!

How to Make Sally S Key Lime Bars

  1. Preheat oven to 350°F (175°C).
  2. In a medium bowl, combine 1 1/2 cups all-purpose flour, 1/2 cup powdered sugar, 1/4 teaspoon salt, and 1/2 cup (1 stick) cold unsalted butter, cut into small pieces.
  3. Using a pastry blender or your fingers, cut the butter into the dry ingredients until the mixture resembles coarse crumbs.
  4. Stir in 1/2 cup chopped pecans.
  5. Press the mixture firmly into the bottom of an ungreased 8x8 inch or 9x9 inch baking pan.
  6. Bake for 15-20 minutes, or until the edges are lightly golden brown.
  7. While the crust is baking, whisk together in a separate bowl: 1 (14-ounce) can sweetened condensed milk, 1/2 cup key lime juice (freshly squeezed from about 6-8 key limes or bottled), 2 large eggs, and 1 teaspoon lime zest.
  8. Pour the filling evenly over the hot, partially baked crust.
  9. Bake for an additional 18-20 minutes, or until the filling is set and no longer jiggles.
  10. Let the bars cool completely in the pan before frosting.
  11. For the frosting, whisk together 1/2 cup (1 stick) unsalted butter, softened; 2 cups powdered sugar; and 2 tablespoons key lime juice until smooth and creamy.
  12. Spread the frosting evenly over the cooled bars.
  13. Garnish with lime zest before serving.
  14. Refrigerate for at least 30 minutes before serving to allow the bars to set completely.
